DO NOW: Please write in your notebooks your opinion of the video and any questions you may have about the video.
We will revisit this video / questions again tomorrow.
TO DO today:
Do Now Q (save for later)
Activity
Review HW

2. INTRODUCTION Walk around the room and examine the objects you see….
Answer the questions on the page…
WHAT IS THE CONNECTION BETWEEN THESE OBJECTS (keep it to your group when you figure it out…)
WE WILL REVIEW AT THE END OF CLASS

3. What is the CONNECTION between all of those things?
TODAY you examined some objects and we determined that the connection was……
ENERGY

5. What is Energy? The ability to do work
The ability to cause motion or change
WHERE DOES MOST OF THE ENERGY COME FROM?

9. How is energy TRANSFERED?
What is meant by conservation of energy?
How is energy transferred between objects or systems?

10. The Law of Conservation of Energy
states that energy can neither be created (produced) nor destroyed by itself.
It can only be transformed/transferred.
Newton’s Cradle

12. Types of Energy KINETIC – energy in progress, a body in motion
Hover board

13. Types of Energy
Potential - The potential to do work, or energy stored not being used yet.
Coal

14. Types of Energy
Mechanical – Sum of kinetic and potential energies.

16. Types of Energy
Thermal – Energy required to change the temperature of something > Heat energy > transfers from warmer objects to cooler ones. video

17. Types of Energy
Chemical - Energy by chemical reactions
Video

18. Types of Energy
Electrical – Energy by electricity video 2

19. Types of Energy
Magnetic - potential energy by magnets or magnetic field
video

20. Types of Energy
Radiant – electromagnetic radiation energy, including light
Light is wavelengths and differed wavelengths produce different colors.
White Light is a combination of all other colors

22. ALBEDO
Radiant light that is not absorbed by the Earth but is reflected back to space.

24. Types of Energy
Elastic – potential mechanical energy stored required to distort volume or shape.
Video 1 2

25. Types of Energy
Gravitational – potential energy due to the force of gravity caused by the attraction of all other masses to the mass of the earth
The potential to fall back to Earth

26. Types of Energy
Sound – sound is produced by vibrations, the effect of mechanical energy propelled by oscillations (waves).

Music

27. Types of Energy
Ionization – the minimum amount of energy required to remove an electron from an atom.

28. Types of Energy
Nuclear energy - is the energy required to split a nucleus of an atom into its component parts
Video Three Mile Island
